I am sure it means exactly what I think it means. If you want a clarification you have but to ask. Gatekeeping rightfuly has a negative connotation when it comes to discriminatory issues towards women and minorities, but as a general word it doesn't necessarily have a negative connotation at all. For example, to become a university professor one often must overcome a series of intentional barriers erected by the senior people of that profession, some of which are communication barriers, some of them political (as in social politics) barriers, as a means of gatekeeping the position of faculty member.
Tell you what, go to a MENSA game day event (I am not a member of MENSA by the way, I just had some brief experiences at their game day events). You will see rules gatekeeping on full display. You will also see it has nothing to do with gender and in fact may well find the majority of people exercising pleasure in that rules gatekeeping is being done by women there.
I am wondering if maybe the only context some people have encountered the word gatekeeping is at it applies to discrimination against women and minorities and have not encountered the word in a context that doesn't involve those issues? It didn't come from that arena of issues. It's a word from the 1920s I believe, which I think started in journalism.
